Abstract

Industrial hemp has attracted public attention in recent years since its planting legalization in the United States in 2018. Hemp exhibits unique advantages compared to cotton in sustainability and physical properties such as lower water consumption for cultivation and high tensile strength as a technical fiber. However, due to the complex chemical composition in hemp fiber, traditional hemp fiber processing has required harsh chemicals to remove the impurities, generating undesirable effluents. One approach toward achieving more sustainable hemp fiber production is to lower chemical requirements by employing enzymatic fiber degumming treatments. Natural gums must be removed to achieve high quality spinnable fibers. This review presents a thorough discussion of hemp fiber composition and structure as prerequisites for subsequent discussion of enzyme reactions on three main substrates in the gum—hemicellulose, lignin and pectin. Understanding the specific chemical structure of each substrate is essential for choosing corresponding enzymes for the treatment. The impacts of different enzymatic hemp degumming treatments are compared and their related characterization methods are assessed. As a result, this article provides the hemp industry with structure–function based guidance on degumming hemp with enzymes and offers strategies for establishing green production approaches to achieve sustainability for the industry.

大麻的酶解脱胶：文献综述

工业大麻自2018年在美国种植合法化以来，近年来引起了公众的关注。与棉花相比，大麻在可持续性和物理性能方面具有独特的优势，例如种植用水量较低，作为技术纤维的拉伸强度高。然而，由于大麻纤维中的化学成分复杂，传统的大麻纤维加工需要使用苛刻的化学品来去除杂质，从而产生不良的废水。实现更可持续的大麻纤维生产的一种方法是通过采用酶纤维脱胶处理来降低化学要求。为了获得高质量的可纺纤维，必须去除天然胶。本文对大麻纤维的组成和结构进行了深入的讨论，为随后讨论三种主要底物——半纤维素、木质素和果胶上的酶反应提供了前提。了解每种底物的特定化学结构对于选择相应的酶进行处理至关重要。比较了不同的酶促大麻脱胶处理的影响，并对其相关的表征方法进行了评价。因此，本文为大麻产业提供了基于结构功能的酶脱胶大麻指导，并提供了建立绿色生产方法的策略，以实现产业的可持续性。

期刊介绍： Cellulose is an international journal devoted to the dissemination of research and scientific and technological progress in the field of cellulose and related naturally occurring polymers. The journal is concerned with the pure and applied science of cellulose and related materials, and also with the development of relevant new technologies. This includes the chemistry, biochemistry, physics and materials science of cellulose and its sources, including wood and other biomass resources, and their derivatives. Coverage extends to the conversion of these polymers and resources into manufactured goods, such as pulp, paper, textiles, and manufactured as well natural fibers, and to the chemistry of materials used in their processing. Cellulose publishes review articles, research papers, and technical notes.
